Source: http://www.doksinet BALLOON TERMINOLOGY ACROPHOBIA: The fear of heights. DEFLATION PORT: The rip panel of the envelope that separates from it to allow hot air to escape quickly. AERONAUT: One who operates or travels in a balloon. AEROSTAT: The balloon itself. ALTIMETER: An instrument to register changes in atmospheric pressure resulting from a change in altitude. It is calibrated to indicate height above mean sea level. APEX: The uppermost point or crown of the balloon envelope where gore ends and load tapes meet. ENVELOPE: The fabric portion of the balloon that holds the hot air. EQUATOR: Where the circumference of the balloon is the greatest. EQUILIBRIUM: The state of balance when the balloons lift equals its weight and becomes buoyant. BALLOONMEISTER: The person responsible for the various balloon activities at a balloon meet. FAHRENHEIT: One of two common temperature scales; the other being Centigrade or Celsius. On a Fahrenheit scale 32o is the freezing point of

water under standard atmospheric pressure. BAROGRAPH: A recording barometer which senses changes in the atmospheric pressure. It records altitude and time. FALSE LIFT: The venturi effect of the wind that causes the balloon to lift off before equilibrium is reached. BASKET: Cockpit of the balloon designed to hold passengers, fuel tanks and the operational control systems. Sometimes it is referred to as the gondola GORE; The lengthy pieces of balloon fabric which taper at each end to form the vertical sections of the envelope. BLAST VALVE: A high pressure fuel valve used to put heat into the envelope. HANDLING LINE: A 50 rope attached near the equator. Used to maintain stability of the balloon during inflation or deflation. BTU: British Thermal Unit. The amount of heat required to raise the temperatures of one pound of water by one degree Fahrenheit. Burners on balloons are rated by their BTU output. BUOYANCY: The tendency of a balloon to float in the air. HEATER: See burner.

INFLATION: The process by which air is forced into the envelope and then heated. KEVLAR: A non conducting material used to replace stainless steel suspension cables. BURNER: The fuel burning device consisting of superheating coils, propane jets and pilot light. KNOT: A unit of speed in nautical miles per hour. CEILING: The height of the lowest layer of clouds above the ground. LAPSE RATE: The decreases in atmospheric temperature with altitude. CHASE CREW: The crew members who follow the balloon in a vehicle to retrieve it after landing. LOAD TAPE: A flat vertical or horizontal webbed nylon strap that takes most of the envelope stress. CROWN LINE: A handling line some 100 long attached to the apex of the balloon. Used to steady the balloon during inflation and deflation. MANEUVERING VENT: A closeable flap operated by a control line which permits hot air to be vented Source: http://www.doksinet Ballooning Timeline 1709 A Brazilian priest, Bartolemeu de Gusmao, demonstrated a

model hot-air balloon to Johan V of Portugal. No . records exists to suggest that any passenger carrying balloon was then built. 1776 Henry Cavendish discovers hydrogen, which was found to be seven times lighter than air. In these early .days, hydrogen was made by mixing sulfuric acid and iron The race to fly was on 1783 June - The Montgolfier brothers, Joseph and Ettienne J. began experimenting with small-scaled hot-air . balloons built out of paper or light fabric. . August - Jaçques A. C Charles launched an unmanned hydrogen balloon, The Globe, which travelled 15 miles (24 km) and reached an altitude of 3000 feet (915m). At the landing in Gonesse, the local peasants were so frightened that they attacked the balloon with pitchforks and scythes, thus destroying it. September - The Montgolfier brothers launched an unmanned hot-air balloon from Versailles. Louis XVI had decreed that the first flight should be flown with animals. A duck, a sheep, and a rooster became the first air

travellers. If it wasnt this flight, then it was had to be another one within the following 2 months November - For the first time in recorded human history, we leave the confines of the Earths surface and take flight among the birds. Over 400,000 Parisians, including Louis XVI and Marie Antoinette, witnessed as the Marquis François dArlendes and Jean-François Pilâtre de Rozier flew in the very first flight in a Mongolfier built hot-air balloon. This flight lasted 25 minutes and covered 7 miles (11 km) December - Just 10 days after the Montgolfier flight, J.AC Charles piloted the first gas balloon flight Also launched in Paris, this flight lasted 2 1/2 hours and covered a distance of 27 miles (43 km). The first recorded change out of a passenger occured on this flight when Charles landed and dropped off his passenger Professor Robert, then took off again. Charles then flew to height of 9000 ft (2750 m) 1784 January - Joseph Montgolfier made his only recorded flight in Le

Fleusselles. This balloon is believed to have had a passenger carrying capacity of more than 30 and the envelope must have been over 700,000 cf (20,000 cubic meters)! This was the largest hot-air balloon ever built until very recently! The flight originated in Lyon, France. September - Vincenzo Lunardi, a minor Italian diploment, piloted the first balloon flight outside of France. A crowd of 100,000, including the Prince of Wales, watched as Lunardi launched his 18,200cf (515 cubic meters) hydrogen balloon from Moorfields, England. He ultimately touched down near Ware November - Frenchman Jean-Pierre Blanchard and American John Jeffries make their first flight. This flight was from Rhedarium Garden, London to the banks of the Thames. 1785 January - Blanchard and Jeffries make the first crossing of the English Channel by balloon. This flight included the very first airmail letter! July - Jean-François Pilâtre de Rozier attempted an English Channel crossing in a hybrid gas/hot-air

balloon. This flight ended in disaster as a fire caused the hydrogen to explode. de Rozier and his passenger Romain were killed. This was the first avaition accident Jean-Pierre Blanchard became the first skydiver as he parachuted out of a gas balloon. 1793 January - After moving to America, Jean-Pierre Blanchard piloted the first known balloon flight in North America in Phildadelphia, PA. George Washington witnessed this flight . Source: http://www.doksinet Name Hot Air Balloon Exam Match the words with their definition. 1. Basket 2. Burner 3. Burner Supports 4. Crown 5. Envelope 6.
